A 500hp 3G automatic would most likely kill the SRT-10 at a red light to 60 or so. Remember that 500HP SRT would make more like 400-450 rear wheel HP on the dyno. Add in lost time in shifting, and a traction issue because of 2 wheel drive with no weight in the rear end and a 500 RWHP cummins auto should blow it away no problem. 60 and above it should become a real race.
